I have a pair of cutters, with about a 3 or 4 inch long razor sharp, replaceable blade, that I keep in my truck. I use those, when I don't have my loppers handy, or can't use them because it would be obvious what I am doing to certain........ uh....... park officials....... uh if I were to do such things, that is........
They are also from the the Man's store. (Harbor Freight)
They cut clean, without any split edges. They are about eight inches or so, long. And Fit in my pocket.
Each of these items listed on here from other contributors, are all worthy of using. Just use what is handy and works for you.
You want a tool, that is handy, and won't crush, or split the boo, or cane. The best tool, is the "one" you like.
